摘　　要：目的：建立正常早孕期妊娠囊的体积参数。方法：选择正常早期单胎妊娠妇女303例，先用腹部容积探头二维模式对妊娠早期妊娠囊进行扫描，常规测量妊娠囊、卵黄囊及胚芽的大小（直径或长度）。再启用三维超声对妊娠囊进行三维图像采集，应用三维容积自动测量技术（VOCAL）测量其体积。结果：妊娠早期，随着孕周增加，妊娠囊体积、胚芽体积及卵黄囊体积均呈增长趋势；妊娠囊胚芽体积比随孕周增大逐渐减少；妊娠囊体积在孕7～10周的相邻两周之间，差异有统计学意义（P〈0．05）；而10周与11周间，差异无统计学意义（P〉0．05）；胚芽体积在孕7～11周的相邻两周之间，差异有统计学意义（P〈0．05）；卵黄囊体积在早孕各孕周的相邻两孕周之间，差异无统计学意义（P〉0．05）。结论：利用三维超声建立正常孕早期妊娠囊的体积参数和变化规律。Objective： To explore the value of three-dimensional ultrasound in early pregnancy volume parameters area. Methods： A total of 303 cases of normal pregnancy were collected. The volume probe using a two- dimensional pattern on the abdomen early pregnancy was used to scan the gestational sac, gestational sac, yolk sac and embryo size which were conventionally measured （diameter or length）. Gestational sac three-dimensional image was then captured, using a three-dimensional volume, each volume was measured by the automatic measurement techniques （VOCAL）. Results： With increasing gestational age, gestational sac size, embryo and yolk sac volume showed volume growth trends; germ gestational sac volume ratio decreased with increasing gestational age, the difference of two weeks gestational sac volume between adjacent 7-10 weeks was statistically significant （P〈0.05）, which was not statistically significant between 10 weeks and 11 weeks; germ volume between adjacent two weeks of 7-11 weeks was significantly different （P〈0.05）; each trimester gestational sac volume between the two adjacent gestation was not significantly different. Conclusion： Three-dimensional ultrasound has a high value in the study of early pregnancy volume parameters.
